  1. Marine Models in CSDMS Circ: 2DFLOWVEL (C), ROMS, POM, Symphonie Wave: WW3 Morph: Fanbuilder SedTrans: Sedtrans05 Sedim: GPM, Dionisos, SedPack, Simsafadim, Sedflux, Sedsim, SimClast GravFlow: Bing, Inflow, Sakura, Wsgfam, Gvg3dp Sub: Compact, LithFlex1, LithFlex2, Subside Source: Plume Misc: Bio, Diffusion Coastal: BarSim, CstASMITA, Integrated: Delft3D Carbonates: CarbGPM, FuzzyReef

  2. Marine Modeling Data Needs • Sea-surface temperature • Winds (speed, direction, wind stress) • Tides • Waves • River mouth discharge • Sediment characteristics of seafloor

  3. Gravity-driven transport in CSMDS Many approaches (DNS, 1D avg’d Chezy balance) CSDMS needs 2D (spatial), depth-avg’d models for turbidity currents, debris flows • Several suitable models exist but are not yet in CSMDS Failure conditions also have to be formulated in 2D • Lee’s GIS approach may be suitable, extends formulation currently in SedFlux

  4. Proof-of-concept ideas • River-ocean coupling in Arctic • Gully formation on continental slope, related to sediment failure and feedback with pore pressure • If models are capable of channel formation, how large would a basin have to be to have a channel run through it? • Couple debris flow and turbidity current models (hard to do) • Deformation of sea floor and feedbacks to deposition and stratigraphy • Compare geometric models and process models of basin sedimentation

  5. Priorities • Development of SedGrid to support a range of marine and coastal/terrestrial modeling projects • Addition of 2D, depth-averaged gravity flow models (turbidity currents and debris flows) to CSDMS; also 2D failure criteria • Create searchable model database • IRF and link SedFlux components with SedGrid
